Purpose

The Object item makes it possible to extend the functionality of VoiceXML beyond its normal capabilities. For example, the VoiceXML standard does not support conference calling. However, if your system supports conference calling, you can write a platform-specific script or application that can be used to take advantage of your system's capabilities. You then use this script or application using the Object item.

Behavior

The Object item takes the values of the properties specified in the following section and uses them to implement and execute the object specified.

If you need to pass data to the object from the application, use the Object Input item. See Object Input.

If the object returns data that you want to use in the application, use the Object Output item. See Object Output.

For more information about using objects in VoiceXML, see "object element" in the W3C VoiceXML 2.0 Recommendation.

Properties

Of the following properties for the Object item, only the Class ID property is required for all objects. The need to use other properties depends on what object you are calling.

Name - Enter the name to identify the object in the call flow.

Class ID - Enter the URI for the object you want to execute.

This URI may be either an absolute or a relative URI. If it is a relative URI, it is interpreted relative to the Codebase property.

Data - Enter the URI that specifies the location of the data for the object.

This URI may be either an absolute or a relative URI. If it is a relative URI, it is interpreted relative to the Codebase property.

Type - Enter the content type of the data specified in the Data property.

Archive - Enter a space-separated list of URIs for archives containing resources relevant to the object.

These resources can include the resources specified by the Class ID and Data properties.

Any relative URIs are interpreted relative to the Codebase property.

Codebase - Enter the base path to use when resolving relative URIs specified by the Class ID, Data, and Archive properties.

The default for this property is the URI of the current document.

Codetype - Enter the content type of the data the system expects when it downloads the object specified by the Class ID property.

If you leave this field blank, the system defaults to the content type specified in the Type property.
